The studies in this dissertation aim at advancing our scientific understandings about physical processes involved in the aerosol-cloud-precipitation interaction and quantitatively assessing the impacts of aerosols on the cloud systems with diverse scales over the globe on the basis of the observational data analysis and various modeling studies. As recognized in the Fifth Assessment Report by the Inter-government Panel on Climate Change, the magnitude of radiative forcing by atmospheric aerosols is highly uncertain, representing the largest uncertainty in projections of future climate by anthropogenic activities. By using a newly implemented cloud microphysical scheme in the cloud-resolving model, the thesis assesses aerosol-cloud interaction for distinct weather systems, ranging from individual cumulus to mesoscale convective systems. This thesis also introduces a novel hierarchical modeling approach that solves a long outstanding mismatch between simulations by regional weather models and global climate models in the climate modeling community. More importantly, the thesis provides key scientific solutions to several challenging questions in climate science, including the global impacts of the Asian pollution. As scientists wrestle with the complexities of climate change in response to varied anthropogenic forcing, perhaps no problem is more challenging than the understanding of the impacts of atmospheric aerosols from air pollution on clouds and the global circulation.
The most comprehensive and richest study undertaken so far of the factors and conditions that will determine the scope and range of shipping and shipping activities in Arctic waters now and in the future. Furthermore, it is the first study comparing the three Arctic transportation corridors, covering a variety of interacting and interdependent factors such as: - geopolitics, military affairs, global warming, sea ice melting, international economic trends, resources, competing modes of transportation, environmental challenges, logistics, ocean law and regulations, corporate governance, jurisdictional matters and rights of indigenous peoples, arctic cruise tourism and marine insurance.
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Chapters "Sonocatalysis: A Potential Sustainable Pathway for the Valorization of Lignocellulosic Biomass and Derivatives", "Valorisation of Biowastes for the Production of Green Materials Using Chemical Methods" and "Green and Sustainable Separation of Natural Products from Agro-Industrial Waste: Challenges, Potentialities, and Perspectives on Emerging Approaches" are available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
This important compendium deals with the primary world problems of global warming and the coming energy crisis. In alternating chapters, it lays out the nature of the two interrelated problems, and specifies the various economic considerations. Thus, it describes the coming shortfall of fossil fuel energy in detail and then presents the economic factors governing possible solutions.Written by two world renowned academics - a physicist who writes about the nature of the problem, and an economist who discusses various scenarios and solutions, this unique must-have book highlights the problem from the point of view of a scientist and an economist.
This volume presents nine chapters prepared by international authors and highlighting various aspects of climate change and water resources. Climate change models and scenarios, particularly those related to precipitation projection, are discussed and uncertainties and data deficiencies that affect the reliability of predictions are identified. The potential impacts of climate change on water resources (including quality) and on crop production are analyzed and adaptation strategies for crop production are offered. Furthermore, case studies of climate change mitigation strategies, such as the reduction of water use and conservation measures in urban environments, are included. This book will serve as a valuable reference work for researchers and students in water and environmental sciences, as well as for governmental agencies and policy makers.
This work examines the waters of marine ports as unique integrated aquatic ecosystems. It regards marine ports as entities comprising components of natural and anthropogenic origin, including pelagic, periphytal and benthal subsystems. Using selected Black and Azov Sea ports as examples, the book discusses the hydrodynamics and water exchange, which are weakened in ports compared with open coastal zones. It reflects consequences of the presence of hydrobionts and the accumulation of organic matter, which are promoted by the variety of hard substrata and the absence of fishery. The book is divided into five main chapters. The first chapter describes the general characteristics of the marine ports at the northern coast of the Black and Azov Seas and their shipping channels. Chapters 2 to 4 discuss the main abiotic and biotic peculiarities of the pelagial, periphytal and benthal subsystems of those marine ports, and chapter 5 deals with tropho-dynamic processes in their ecosystems. A concluding section reflects recommendations how the ecosystems of ports in non-tidal seas may be ameliorated.
This book is a systematic compilation of the most recent body of knowledge in the rapidly developing research area of greenhouse gas interaction with clay systems. Unexpected results of the most recent studies - such as unusually high sorption capacity and sorption hysteresis of swelling clays -stimulated theoretical activity in this fascinating field. Classical molecular dynamics (MD) explains swelling caused by intercalation of water molecules and to a certain degree of CO2 molecules in clay interlayer. However, unusual frequency shifts in the transient infrared fingerprints of the intercalated molecules and the following accelerated carbonation can be tackled only via quantum mechanical modeling. This book provides a streamlined (from simple to complex) guide to the most advanced research efforts in this field.
The aim of this book is to provide information to scientists and local government to help them better understand the particularities of the local climate. Climate change is one of the biggest challenges to society. It can lead to serious impacts on production, life and environment on a global scale. Higher temperatures and sea level rise will cause flooding and water salinity problems which bring about negative effects on agriculture and high risks to industry and socio-economic systems in the future. Climate change leads to many changes in global development and security, especially energy, water, food, society, job, diplomacy, culture, economy and trade. The Intergovernmental Panel on Climate Change (IPCC) defines climate change as: "Any change in climate over time, whether due to natural variability or as a result of human activity." Global climate change has emerged as a key issue in both political and economic arenas. It is an increasingly questioned phenomenon, and progressive national governments around the world have started taking action to respond to these environmental concerns.
This is the first environmental history of Russia's steppes. From the early-eighteenth century, settlers moved to the semi-arid but fertile grasslands from wetter, forested regions in central and northern Russia and Ukraine, and from central Europe. By the late-nineteenth century, they had turned the steppes into the bread basket of the Russian Empire and parts of Europe. But there was another side to this story. The steppe region was hit by recurring droughts, winds from the east whipped up dust storms, the fertile black earth suffered severe erosion, crops failed, and in the worst years there was famine. David Moon analyses how naturalists and scientists came to understand the steppe environment, including the origins of the fertile black earth. He also analyses how scientists tried to understand environmental change, including climate change. Farmers, and the scientists who advised them, tried different ways to deal with the recurring droughts: planting trees, irrigation, and cultivating the soil in ways that helped retain scarce moisture. More sustainable, however, were techniques of cultivation to retain scarce moisture in the soil. Among the pioneers were Mennonite settlers. Such approaches aimed to work with the environment, rather than trying to change it by planting trees or supplying more water artificially. The story is similar to the Dust Bowl on the Great Plains of the USA, which share a similar environment and environmental history. David Moon places the environmental story of the steppes in the wider context of the environmental history of European colonialism around the globe.
ulian Steward Award 2006 Runner-Up In this highly readable account . . . Checker has written a fine book. Assigned to students interested in urbanism, science and technology studies, race relations in the United States, environment, or social movements, the book is sure to spark thoughtful conversation. -American Anthropologist Melissa Checker's absorbing story is a portrait of America. Polluted Promises showcases the complex links between toxic waste and race, and the hope-filled journeys of environmental activists who are wise, strong, and spiritual in their fight against toxic waste--and for their lives. Checker is doing public anthropology for social justice. -Carol Stack, author of All Our Kin I hope that (this book) doesn't get pidgeonholed as a dry, academic treatise, because it is anything but that. It is a wonderfully written account of the struggles by the residents of Hyde Park, a neighborhood in Augusta, Georgia, to undo decades of...environmental racism. -In Brief A very rich, organized, and theoretically interesting ethnographic case study of environmental activism. Checker beautifully recounts how the issues of race emerged and were manipulated in social organizing against environmental poisoning. -George E. Marcus, author of Ethnography through Thick and Thin Polluted Promises is a substantial accomplishment. It grounds the notion of environmental justice wonderfully in practical terms, in the theoretically sophisticated and empathetic examination of Hyde Park. -Adolph Reed, Jr., author of Class Notes: Posing As Politics and Other Thoughts on the American Scene A sweeping and brilliant account of a struggle for environmental justice. With clarity and honesty, Checker adroitly exploits the interconnection of race, environment, and civil rights. This is an authoritative and courageous book that should be essential reading for everyone interested in environmental justice. -Bunyan Bryant, editor of Environmental Justice: Issues, Policies, and Solutions Over the past two decades, environmental racism has become the rallying cry for many communities as they discover the contaminations of toxic chemicals and industrial waste in their own backyards. Living next door to factories and industrial sites for years, the people in these communities often have record health problems and debilitating medical conditions. Melissa Checker tells the story of one such neighborhood, Hyde Park, in Augusta, Georgia, and the tenacious activism of its two hundred African American families. This community, at one time surrounded by nine polluting industries, is struggling to make their voices heard and their community safe again. Polluted Promises shows that even in the post-civil rights era, race and class are still key factors in determining the politics of pollution. Melissa Checker teaches in the Department of Urban Studies, Queens College/CUNY. She is co-editor of Local Actions: Cultural Activism, Power, and Public Life. She is donating all of her proceeds from this book to the Hyde and Aragon Park Improvement Committee.
In tropical latitudes, monsoons trigger regimes of strong seasonal rainfall over the continents. Over the West African region, the rainfall has shown a strong variability from interannual to decadal time scales. The atmospheric response to global sea surface temperatures is the leading cause of rainfall variability in the West African Sahel. This thesis explores changes in the leading ocean forcing of Sahelian rainfall interannual variability. It anaylzes the dynamical mechanisms at work to explain the non-stationary sea surface temperature-forced response of anomalous rainfall. The underlying multidecadal sea surface temperature background is raised as a key factor that favors some interannual teleconnections and inhibits others. Results of this thesis are relevant for improving the seasonal predictability of summer rainfall in the Sahel.
The debate on how mankind should respond to climate change is diverse, as the appropriate strategy depends on global as well as local circumstances. As scientists are denied the possibility of conducting experiments with the real climate, only climate models can give insights into man-induced climate change, by experimenting with digital climates under varying conditions and by extrapolating past and future states into the future. But the nature of models is a purely representational one. A model is good if it is believed to represent the relevant processes of a natural system well. However, a model and its results, in particular in the case of climate models which interconnect countless hypotheses, is only to some extent testable, although an advanced infrastructure of evaluation strategies has been developed involving strategies of model intercomparison, ensemble prognoses, uncertainty metrics on the system and component levels. The complexity of climate models goes hand in hand with uncertainties, but uncertainty is in conflict with socio-political expectations. However, certain predictions belong to the realm of desires and ideals rather than to applied science. Today s attempt to define and classify uncertainty in terms of likelihood and confidence reflect this awareness of uncertainty as an integral part of human knowledge, in particular on knowledge about possible future developments. The contributions in this book give a first hand insight into scientific strategies in dealing with uncertainty by using simulation models and into social, political and economical requirements in future projections on climate change. Do these strategies and requirements meet each other or fail?

Drawing on concepts in political economy, political ecology, justice theory, and critical development studies, the authors offer the first comprehensive, systematic exploration of the ways in which adaptation projects can produce unintended, undesirable results. This work is on the Global Policy: Next Generation list of six key books for understanding the politics of global climate change.
At the recent UN Climate Change Conferences in Copenhagen, Cancun and Durban, the developed nations promised hundreds of billions of dollars in financial aid to help developing countries overcome global climate change dangers. The developed nations will need to spend many more billions to limit their own greenhouse gas pollution, the main cause of global warming and climate change. Will all this money and effort be wasted? This book argues that nearly all of the world's climate policy makers and expert advisors have been making tragic mistakes that ensure the failures of climate change mitigation attempts.The great majority of climate change programs, from American congressional bills to cap-and-trade economic incentive schemes to the Kyoto Protocol and other international treaties, rely on greenhouse gas emissions-reduction targets that will prove "too little, too late" by deferring strict pollution controls too far into the future. The inadequate emissions-reduction measures also will not be able to bridge the gap between the highest priorities of developed and developing nations. Vast discharges of greenhouse gases authorized by weak emissions-reduction programs in the next several decades virtually guarantee that the cumulative concentration of greenhouse gases in the atmosphere will keep increasing while climate change continues to grow worse.Rather than adopting ineffectual emissions-reduction programs that cannot limit the cumulative concentration of greenhouse gases in the air, this book proposes a shift to a "clean" technology-replacement strategy that could support current lifestyles and expanding economic development without further damaging our climate. The only way to reduce the greenhouse gas levels in the atmosphere enough to decrease climate change hazards is to replace large pollution sources as rapidly as feasible in as many industrial sectors and geographic regions as possible with "clean" alternative technologies, processes, and methods.
Climate change and ongoing transformation processes in economy and agriculture will have strong and multiple impacts in the Baltic region. In particular coastal zones face increasing hazards, e.g. due to sea level rise or changes in riverine nutrient loads and eutrophication. These changes also offer a wide range of new opportunities in the Baltic Region. Adaptation measures are needed but require a thorough and spatially differentiated understanding of underlying ecological, economic and social processes. Sixteen contributions by authors from eight countries give a comprehensive overview of these changes, their consequences and practical challenges with focus on coastal zones. Besides risks, the chances and opportunities of changes for the region are addressed and adaptation examples and strategies are given. The practitioners perspective and their demands are integrated in the various contributions.
New technologies and assessment methods create improved opportunities to monitor and predict the onset of natural disasters in the era of global warming. Researchers continue to evaluate the changes in weather patterns in order to better understand natural phenomena. Extreme Weather and Impacts of Climate Change on Water Resources in the Dobrogea Region presents a descriptive environmental resource focused on a Romanian region affected by the changing climate. In discussing methods of assessment, monitoring, and prediction, the research included in this publication is an essential resource for policymakers, academicians, researchers, advanced-level students, technology developers, and government officials who wish to expand their research exposure to pertinent topics related to flooding and droughts due to climate change.
Drylands in East Asia (DEA) are home to more than one billion people with an environment vulnerable to natural and anthropogenic changes. One of the critical needs in the region is to fully understand how dryland ecosystems respond to the changing climate and human activities in order to develop strategies to cope with continued climate change. This book provides state-of-the-art knowledge and information on drylands ecosystem dynamics, changing climate, society, and land use in the region. In addition to the synthesis of the existing research and knowledge of DEA, the book provides a role model for regional ecological assessment. With a wide spectrum of contributions from experts around the globe, the book should be of interest to researchers and students both internationally and in East Asia. Lessons learned from this synthesis effort in DEA should be useful for developing climate adaptation strategies for other similar regions around the globe.
Recent developments in air pollution modelling are explored as a series of contributions from researchers at the forefront of their field.

Additionally, this work also examines the relationship between air quality and human health and the effects of climate change on air quality. The work derives from a series of papers presented at the 33rd International Technical Meeting on Air Pollution Modelling and its Application held in Miami, USA, August 27 - 31, 2013.The book is intended as reference material for students and professors interested in air pollution modelling at the graduate level as well as researchers and professionals involved in developing and utilizing air pollution models."
This book provides extensive and comprehensive information to researchers and academicians who are interested in radionuclide contamination, its sources and environmental impact. It is also useful for graduate and undergraduate students specializing in radioactive-waste disposal and its impact on natural as well as manmade environments. A number of sites are affected by large legacies of waste from the mining and processing of radioactive minerals. Over recent decades, several hundred radioactive isotopes (radioisotopes) of natural elements have been produced artificially, including 90Sr, 137Cs and 131I. Several other anthropogenic radioactive elements have also been produced in large quantities, for example technetium, neptunium, plutonium and americium, although plutonium does occur naturally in trace amounts in uranium ores. The deposition of radionuclides on vegetation and soil, as well as the uptake from polluted aquifers (root uptake or irrigation) are the initial point for their transfer into the terrestrial environment and into food chains. There are two principal deposition processes for the removal of pollutants from the atmosphere: dry deposition is the direct transfer through absorption of gases and particles by natural surfaces, such as vegetation, whereas showery or wet deposition is the transport of a substance from the atmosphere to the ground by snow, hail or rain. Once deposited on any vegetation, radionuclides are removed from plants by the airstre am and rain, either through percolation or by cuticular scratch. The increase in biomass during plant growth does not cause a loss of activity, but it does lead to a decrease in activity concentration due to effective dilution. There is also systemic transport (translocation) of radionuclides within the plant subsequent to foliar uptake, leading the transfer of chemical components to other parts of the plant that have not been contaminated directly.
Ecosystems are often examined from a ecological perspective because of the importance of biodiversity and ecosystem services. Ecosystems of different types and scales are under increasing pressure due to natural and human induced changes. Climate change and the disasters it causes, are a major driver affecting ecosystems and services. Several studies have provided evidence that a healthy ecosystem helps in reducing the impacts of climate change and disasters. This book makes a case for ecosystem-based adaptation by arguing that ecosystems and its services are critical in the climate change and disaster risk reduction fields. Consequently, the monitoring and regulation of ecosystems need to be linked to a regular governance and institutional mechanism and be reflected in a more action-oriented agenda.
EPR of Free Radicals in Solids: Trends in Methods and Applications, 2nd ed. presents a critical two volume review of the methods and applications of EPR (ESR) for the study of free radical processes in solids. Emphasis is on the progress made in the developments in EPR technology, in the application of sophisticated matrix isolation techniques and in the advancement in quantitative EPR that have occurred since the 1st edition was published. Improvements have been made also at theoretical level, with the development of methods based on first principles and their application to the calculation of magnetic properties as well as in spectral simulations. EPR of Free Radicals in Solids II focuses on the trends in applications of experimental and theoretical methods to extract structural and dynamical properties of radicals and spin probes in solid matrices by continuous wave (CW) and pulsed techniques in nine chapters written by experts in the field. It examines the studies involving radiation- and photo-induced inorganic and organic radicals in inert matrices, the high-spin molecules and metal-based molecular clusters as well as the radical pro-cesses in photosynthesis. Recent advancements in environmental applications in-cluding measurements by myon resonance of radicals on surfaces and by quantitative EPR in dosimetry are outlined and the applications of optical detection in material research with much increased sensitivity reviewed. The potential use of EPR in quantum computing is considered in a newly written chapter. This new edition is aimed to experimentalists and theoreticians in research involving free radicals, as well as for students of advanced courses in physical chemis-try, chemical physics, materials science, biophysics, biochemistry and related fields.
In this updated and expanded second edition, new literature has been added on contaminant fate in the soil-subsurface environment. In particular, more data on the behavior of inorganic contaminants and on engineered nanomaterials were included, the latter comprising a group of emerging contaminants that may reach the soil and subsurface zones. New chapters are devoted to a new perspective of contaminant geochemistry, namely irreversible changes in pristine land and subsurface systems following chemical contamination. Two chapters were added on this topic, focusing attention on the impact of chemical contaminants on the matrix and properties of both liquid and solid phases of soil and subsurface domains. Contaminant impacts on irreversible changes occurring in groundwater are discussed and their irreversible changes on the porous medium solid phase are surveyed. In contrast to the geological time scale controlling natural changes of porous media liquid and solid phases, the time scale associated with chemical pollutant induced changes is far shorter and extends over a human lifetime scale ." |
